UNTTED %TATE PTENT @FFT@E DAISY FLEMING, OF SACRAMENTO, CALIFOENIA,ASSIGNOR OF ONE-HALF TO WILLIAM T. REMINGTON, OF SACRAIVIENTO,CALIFORNIA.

SYRINGE.

To all 'whom it may concern Be it known that I, Dasr FLEMING, a citizenof the United States residing at Sacramento, in the county of Sacramentoand State of California, have invented new and useful Improvements inSyringes, of which the following is a specification.

This invention relates to a syringe.

The Object of the present invention is to provide a simple andsubstantial syringe, so constructed that the nozzle portion may beseparated for the purpose of gaining access to the interior of thenozzle when it is desired to cleanse or disinfect same.

The invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which- Figure 1 is a sideelevation of the syringe in perspective, showing the parts assembled.Figs. 2 and 3 are perspective views of the different parts separated.Fig. 4 is a cross section of the nozzle showing a slight modification ofsame.

The Object of the present invention is to provide a syringe especiallyconstructed to allow access to the interior of the nozzle when it isdesired to cleanse or disinfect same. In places where water is extremelyhard and for other various reasons, the interior of the tube becomescoated with a hard coating of deposit of lime, or other foreignsubstance, which it is impossible to thoroughly remove under ordinaryconditions.

In the present construction here shown, the nozzle is made in two mainsections 2 and 3, which` when separated, entirely open the interiorfiuid passage of same, as shown in Fig. 2. These two halves are unitedand nterlocked in position by the following means:

The main portion of the nozzle, as 3, is provided with a perforation 4,for the purpose of receiving an interlocling pin 5, secured to theremovable portion '2. The main portion 3 is also provided with adovetail or undercut portion 6 which will prevent the removable section2 from being lifted in a vertical line when separating the two halves.The opposite ends of the sections 2 and 3 are provided with threadedportions 7 adapted to receive a coupling 8, internally threaded as at 9,for this purpose.

Specificaton of Letters Patent.

Application filed August 28, 1812.

Patented June 10, 1913.

Serial No. 717,454,

The dovetail portions having been engaged and the pin 5 interloclredwith the perforation 4 in the main portion 3 of the nozzle, it is onlynecessary to bring the end portions together and secure the coupling 8by screwing it over the threaded portions 7. The coupling 8 is providedwith any suitable extension, as 10, for the purpose of receiving arubber connection, as the hose or tube 11.

For the purpose of insuring a tight joint along the meeting edges of thetwo sections 2 and 3, it is possible to accomplish this by giving thesection 2 a little greater conveXity than the main portion 3. Thiscauses the meeting edges to be brought into forcible contact when lockedinto position and they are forced together with more or less pressurecaused by the spring action of the member 2 and will thus produce atight joint.

In Fig. 4: of the drawings I have shown a slight modification in which atight joint between the meeting edges of the parts 2 and 3 of the nozzleis accomplished by providing V-shaped projections 12 on the portion 'Zand the grooves 13 in the main portion 3. This provides a greatercontact area between the sections, thus lessening the possibility of anyleakage between same. Water or other fluid passing through the centralchamber 14 of the nozzle is ej-ected through suitable openings, as 15,Connecting with the central channel 14. These openings 15 may bepositioned in suitable grooves or riflings 16 formed or cut in thesurface of the discharging end of the nozzle.

The nozzle is neat in appearance, simple and substantial inconstruction, and reliable in its actions. The construction does notrequire that it be made of larger Sizes than usual.

The materials and finish of the several parts of the nozzle are such asexperience and judgment of the manufacturer may dictate.

I wish it understood that various changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended claims, and that I do not wish to limit myself to the specificdesign and construction here shown.

Having thus described my invention, what I Claim and desire to secure byLetters Patent, is

1, A syringe comprising a longitudinally divided body portion a Centralfiuid pas sage in said body portion, having a plurality of disohargeopenings communioating With said Central passage, means for interlockingthe longitudinaliy divided body portions, said means eomprisingdo-vetailed interlocking portions in the discharge end of the dividedbody portions, and segmental portions at the receiving end adapted to beinserted into a looking ooupling.

2. A syringe eomprising a longitudinaliy divided body portion, a oentralfluid passage in said body portion, having a plnrality of disohargeopenings communieating With said central passage, means for interioekingthe longitudinaliy divided body portions, said means comprisingdovetailed interlooking portions in the disoharge end of the dividedbody portions, and threaded segmental portions at the receiving endadapted to screw into a couplin 3. A syringe oomprising a longitudinallydivided body portion, a Central fiuid passage in said body portion,having a plurality of discharge openings oommunioating With said Centralpassage, means for interlooking the longitudinally divided bodyportions, said means oomprising dovetailed interlooking portions in thedischarge end of the divided body portions, threaded segmental portionsat the receiving end adapted to screw into a oonpiing, and means forpreventing side movement of the parts With relation to each other, saidmeans comprising an interlocking pin and socket.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing Witnesses.
